I have an LWC embedded in a flow that has a custom footer. Whenever to click on the custom buttons to navigate the next screen, I get the following error:

Uncaught Action failed: flowruntime:flowRuntime$controller$handleNavigate [The 'NEXT' navigation option isn't supported on this screen. Replace it with one of the available navigation options: FINISH.]

Not sure how or why I am getting the error when the 'NEXT' option is in this.availableActions. The flow navigates to the next screen but I still get the error. The weirdest part is that it complains about the opposite if I try to use 'FINISH'.

Here is the snippet of the code:

let navigationEvent;

if (this.availableActions.find(action => action === "FINISH")) {
    navigationEvent = new FlowNavigationFinishEvent();
} else if (this.availableActions.find(action => action === "NEXT")) {
    navigationEvent = new FlowNavigationNextEvent();

try {
} catch (e) {
  • is the component exposed to Flow screen using <target>lightning__FlowScreen</target> in meta xml? Commented Nov 26, 2019 at 20:47
  • Yes, it is. The component is currently being used with a flow.

  • Peter, do you have a case number for that? Commented Mar 2, 2020 at 21:40
  • @user76556 Were you able to solve your issue? I am getting an issue when dispatching 'FlowNavigationFinishEvent' on the click of a 'button in the LWC component. When I click on the button, It shows '[NoErrorObjectAvailable] Script error.' after dispatching the event.

Not sure if you are still looking for answer to this question but using documentation provided here: https://developer.salesforce.com/docs/component-library/bundle/lightning-flow-support/documentation

I was able to make flow actions work using following code:

    handleButtonClick(event) {
        var actionClicked = event.target.name;
        var navigationEvent;
        if (actionClicked === 'Next') {
            navigationEvent = new FlowNavigationNextEvent();
        } else if (actionClicked === 'Finish') {
            navigationEvent = new FlowNavigationFinishEvent();
        } else if (actionClicked === 'Pause') {
            navigationEvent = new FlowNavigationPauseEvent();
        } else if (actionClicked === 'Back') {
            navigationEvent = new FlowNavigationBackEvent();
        try {
        } catch (ex) {
            console.log('Exception: ' + ex);

Call above JS function on button click and pass in name. Your button should look like:

    <button onclick={handleButtonClick} id="Back" name="Back" title="Back">Back</button>

Hope this helps.

  • How do we remove the custom footer and use the above buttons instead?

You'll still need to have the navigation options you want to fire selected in the navigation options
